Description

Technical Field

[0001] The invention relates to the technical field of mold auxiliary positioning tooling, and in particular to a powder metallurgy mold auxiliary positioning tooling and a use method thereof. Background Art

[0002] In the production process of powder metallurgy, the design and precise positioning of the mold are crucial. The mold not only needs to withstand high temperature and high pressure environment, but also must ensure the uniformity and stability of the formed powder particles during the sintering process. Traditional mold positioning methods usually rely on simple mechanical devices, such as positioning pins, clamps, etc. Although these methods can meet the positioning requirements to a certain extent, they still have some limitations in practical applications. First of all, when positioning the powder metallurgy mold, the positioning plate is manually adjusted to clamp the front and back and left and right ends of the stamping mold. This is not only time-consuming and labor-intensive, but also easy to cause inaccurate mold positioning, thereby affecting the stability and reliability of the stamping process. Secondly, in order to ensure the stamping accuracy, the operator needs to fix an additional buffer component separately. The steps are cumbersome and there is no way to ensure that the mold will not be displaced or offset during the stamping process after the positioning is completed. Summary of the invention

[0003] The object of the present invention is to provide a powder metallurgy mold auxiliary positioning tool and a method for using the same. Through the positioning and adjustment mechanism cooperating with the clamping of the card sleeve frame, this automated positioning and adjustment method greatly improves the adjustment efficiency, avoids the cumbersome operation of traditional manual adjustment, reduces manual intervention, and avoids the deviation and uneven force that may occur when the positioning plate is clamped. The positioning and adjustment mechanism drives the anti-movement component to move while driving the card sleeve frame to move. The operator does not need to additionally fix the anti-movement component, which reduces the operation steps and improves work efficiency. The anti-movement component moves synchronously with the card sleeve frame to ensure that the relative position between the two is always stable and can adapt to the needs of different molds. Whether in the initial adjustment or in the production process, only the positioning of the card sleeve frame needs to be adjusted, and the anti-movement component will automatically adjust accordingly, providing better adaptability. The positioning plate is in close contact with the base under the adjustment of the screw. After the positioning is completed, the stamping mold can be effectively fixed to reduce its possible movement or offset during operation, thereby enhancing the stability of the mold, ensuring the consistency and reliability of the stamping process, and solving the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a powder metallurgy mold auxiliary positioning tooling, comprising a base, a lower support plate is arranged above the base, an upper support plate is arranged at the upper end of the lower support plate, a stamping die is arranged above the upper support plate, a sleeve frame is arranged on both sides of the stamping die, an anti-slip assembly is fixedly arranged on the sleeve frame, the sleeve frame is connected to the upper support plate through a positioning and adjustment mechanism, circular holes are provided inside the upper support plate and the lower support plate, movable grooves are provided on both sides of the circular hole, a hydraulic cylinder is fixedly installed on the upper end of the base, a top plate is provided on the piston rod of the hydraulic cylinder, a limiting groove is provided inside the top plate, a limiting block matched with the limiting groove is provided at the bottom of the stamping die, the lower support plate is connected to the base through a cylinder, a positioning rod is provided at the bottom of the upper support plate, and a groove matched with the positioning rod is provided on the lower support plate.

[0006] Preferably, the anti-movement assembly includes a support arm, a support is provided on one side of the support arm, and a U-shaped seat is provided on the other side of the support arm. The ferrule frame is fixed by a positioning block inside the support cooperating with a positioning groove provided in the ferrule frame.

[0007] Preferably, a guide rod passes through the interior of the U-shaped seat, both ends of the guide rod are fixedly connected to the fixing ears, and the fixing ears are fixedly connected to the support arms, and the upper and lower ends of the U-shaped seat are fixedly connected to the fixing ears through springs, and the springs are located outside the guide rod.

[0008] Preferably, a fixed seat is provided below the U-shaped seat, and the fixed seat and the support arm are an integrated structure, an adjustable screw is provided inside the fixed seat, one end of the screw extends to the outside of the fixed seat and is connected to a positioning plate, and an anti-slip pad is provided at the bottom of the positioning plate.

[0009] Preferably, the positioning and adjustment mechanism includes a slide seat, and two slide seats are provided, the upper ends of the two slide seats are slidably provided with a slide groove, and the slide groove is fixedly connected to the sleeve frame, and an electric push rod is provided at the upper end of one of the slide seats, and the electric push rod is fixed to the slide seat through a mounting plate.

[0010] Preferably, a driving seat is fixedly provided at one end of the electric push rod, and both sides of the driving seat are transmission-connected to the slide slot via connecting rods.

[0011] The present invention provides another technical solution: a method for using a powder metallurgy mold auxiliary positioning tool, comprising the following steps: Step 1: Adjust the height of the top plate by driving the hydraulic cylinder so that the top plate is higher than the upper support plate, so that the card sleeve frame can be smoothly connected with the stamping die, and then place the stamping die on the top plate through the cooperation of the limit groove and the limit block; Step 2: Start the electric push rod to control the driving seat to move forward. Under the action of the connecting rod, the slide grooves on both sides can slide towards each other, so that the card sleeve frame is close to the stamping die until the stamping die is clamped, and then the card sleeve frame and the stamping die are fixed with screws; Step 3: After the ferrule frame and the stamping die are fixed, manually rotate the adjusting screw to drive the positioning plate down until the positioning plate is close to the base, thereby completing the positioning of the stamping die; Step 4: Use the cylinder to control the lower support plate to move away from the upper support plate to ensure that the upper support plate and the structure on the upper support plate can move normally. When the stamping die is stamping, the die moves downward under the extrusion of the press, so that the support and the U-shaped seat move vertically in the support arm. The spring is deformed by the extrusion, producing a buffer to offset the die movement caused by stamping and ensure the stamping accuracy of the die.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1.

The connection between the card sleeve frame and the stamping die is fixed with screws to ensure that the die is not easy to loosen during the stamping process, thereby improving the stability and safety of the die and reducing the operating risk. Compared with manually adjusting the positioning plate to clamp and position the front and back and left and right ends of the stamping die, the positioning and adjusting mechanism of the invention cooperates with the clamping of the card sleeve frame. This automated positioning and adjustment method greatly improves the adjustment efficiency, avoids the cumbersome operation of traditional manual adjustment, reduces manual intervention, and avoids the deviation and uneven force that may occur when the positioning plate is clamped.

[0013] 2. The invention proposes a powder metallurgy mold auxiliary positioning tool and a method of using the same. The design of the anti-movement component enables the mold to effectively resist the movement phenomenon when subjected to extrusion force, ensures the stability of the mold during the stamping process, thereby extending the service life of the mold and reducing maintenance costs. The positioning adjustment mechanism drives the anti-movement component to move while driving the card sleeve frame to move, thereby simplifying the operation process. The operator does not need to additionally fix the anti-movement component, which reduces the operation steps and improves work efficiency. The anti-movement component moves synchronously with the card sleeve frame, ensuring that the relative position between the two is always stable, and can adapt to the needs of different molds. Whether in the initial adjustment or in the production process, only the positioning of the card sleeve frame needs to be adjusted, and the anti-movement component will automatically adjust accordingly, providing better adaptability. The positioning plate is in close contact with the base under the adjustment of the screw. After positioning is completed, it can effectively fix the stamping mold and reduce its possible movement or offset during operation, thereby enhancing the stability of the mold and ensuring the consistency and reliability of the stamping process.
